Video compression is a crucial process that reduces the size of video files, making them easier to store, transmit, and stream. It involves encoding techniques that eliminate redundant or unnecessary data, resulting in smaller file sizes without significant loss of quality.
There are two types of video compression: lossless and lossy. Lossless compression preserves all the original data, but the file sizes are still relatively large. Lossy compression, on the other hand, achieves higher compression ratios by discarding some data that is less noticeable to the human eye.
Common video compression algorithms include MPEG, H.264, and HEVC. These algorithms use various methods such as spatial and temporal redundancy reduction, transform coding, and quantization to compress video files efficiently.
